摘　　要：【目的】分析泥石流对浙西某抽水蓄能电站工程下水库的影响。【方法】基于地形地貌、物源条件、水系分布和人类工程活动等,对下水库主沟泥石流形成条件进行分析,调查泥石流堆积物情况,并对主沟泥石流形成临界条件与过程进行研究。【结果】研究结果表明:根据泥石流运动-动力学特征分析主沟泥石流为轻度易发,泥石流类型为沟谷降雨型低频大型稀性泥石流,堵河可能性极低,危害性较小,以预防为主。【结论】研究成果对该抽水蓄能电站下水库库址选择及水工工程设计具有重要意义,可为开展抽蓄电站泥石流调查提供借鉴和指导。[Purposes]To analyse the impact of mudslides on the reservoir under a pumped storage power station project in western Zhejiang.[Methods]The formation conditions of debris flow in the main chan⁃nel of the lower reservoir were analyzed based on topography,provenance conditions,water system distri⁃bution,and human engineering activities.The debris flow deposits were investigated and analyzed,and the critical conditions and process of debris flow formation in the main channel were studied.[Findings]The results showed that,based on the motion-dynamic characteristics analysis,the debris flow in the main gully was classified as low-frequency,large-scale,rare gully rainfall-type flows The possibility of blocking the river was very low,the harm was small,and preventive measures should be prioritized.[Con⁃clusions]The research results are significant for the site selection and hydraulic engineering design of the lower reservoir of the pumped storage power station,and could provide reference and guidance for the investigation of debris flow in the pumped storage power station.
